2.

DEFINITION

For purposes of this Guidelines, the following definitions shall apply:

2.1 Accreditation - The procedure by which the DPWH gives formal recognition, under duly established rules and regulations, that a company is competent to operate an asphalt cement concrete batching plant or a Portland cement concrete batching plant and supply DPWH project requirements.
2.2 Asphalt Concrete Batching Plant - an assembly of mechanical and electronic equipment where aggregates, hydrated lime and additives (optional) are blended, dried, heated and mixed with asphalt cement to produce hot mix asphalt and/or asphalt cement with solvent to produce cold mix asphalt meeting specified requirements.
2.3 Portland Cement Concrete Batching Plant - an assembly of mechanical and electronic equipment where a satisfactory mix proportion of water, cement, aggregates and admixtures (if necessary) are accurately measured and weighed to produce concrete mix meeting specified requirements.
2.4 Stationary Plant  -  a plant that is located at a permanent site.
2.5 Portable Plant - a plant that can transferred from one jobsite to another.  
2.6 Inspection/Assessment - evaluation of facilities, capabilities and its conformity by measuring, observing or testing the relevant characteristics of raw materials and the finished product in accordance with the prescribed standards.
